V'7 Claims.

This invention relates to that class of devices intended to supportrolls of wrapping paper and to mechanism for cutting the paper from therolls in desired lengths.

An object of the present improvement is to provide a combination supportandl cutting mechanism whereby the latter may be adjusted relative tothe support so that regardless of the position of the support, whethermounted upon the counter or wall surface, the cutting mechanism may bearranged for proper working-operation.

Another object of the invention is to provide novel cutting means in theform of a bar with the paper so arranged relative thereto that it may beconveniently grasped at any point along its edge for the tearing thereofWithout the need of iirst turning the roll so as to advance the paper asis now the common practice with the ordinary type of cutters.

It is also an object of the invention to provide a mechanism of thiskind which is extremely simple in its construction, reliable in itsoperation and one which is comparatively cheap or economical tomanufacture.

With these and other objects in view, as will appear as the descriptionproceeds, the invention consists in the novel features of construction,combination of elements and arrangement of parts hereinafter to be fullydescribed and pointed out in the subjoined claims.

Fig. 7 is a vertical longitudinal sectional viewV Referring tothedrawings in detail, numeral 1 designates the paper roll supportingstructure in its entirety and comprising the upstanding end members orbrackets 2 which are in this instance cast and each formed with asupporting foot 3 for attachment to a counter, wall or the likesupporting surface. The lower ends of the brackets may be connected ifdesired by a bar 4 for the convenient spacing ofthe brackets during theerection thereof to a supporting base and for holding the same connectedfor shipping or handling purposes.

Carried by the upper or outer ends of the brackets 2 are adapter members5 which in certain positions of the brackets 2 serve as extensions forthe latter and in turn carry at their outer ends the cutting mechanismdesignated generally by the numeral 6. The adapter members 5 which havebeen designed particularly for the proper positioning of the cuttingmechanism relative to the paper roll, are each formed with a disk likeend 7 to conform in shape with the attaching ends of the brackets 2.Passing through the center of the disk 7 is a threaded fastening elementor screw 8 which serves to rigidly unite the adapter member to thebracket support 2. It will be noted from reference to the drawings andparticularly Figs. 6, 8 and 9, that the adapter members 5 are in eachcase arranged vertically whereas the brackets 2 may be positionedvertically, inverted or horizontally. This is an important feature inthat it enables the paper roll support to be mounted either on top ofthe counter, its under surface or on a Vertical wall without alteringthe construction or substituting parts of the support. To hold themembers 5 in correct position relative to the brackets 2, the disk likeends 7 are formed with lightly struck-up projections 9 which arereceived Within similarly shaped depressions 10 formed in the brackets2. The in` ter-locking relationship of the projections 9 and thedepressions 10 also prevent axial rotation of the adapter members 5 withrespect to the brackets 2 during the use of the supporting structure.

Provided upon the inner surfaces of the adapter members 5 and locatedatthe inner ends thereof are bearingrflanges 11 which are each providedwith an arcuate socket 12 for the reception of the shaft 13 passingcentrally through the paper roll 14. The sockets 12 are slightly spacedfrom the members 5 to provide spaces for the enlargements or heads 15formed with the outer ends of the shaft 13.A 'The heads 15 serve tokprevent longitudinal sliding movement of the shaft and also formconnections between the :shaft and the sup- Ydi eil

porting brackets to brace the latter at their upper ends.

The cutting mechanism 6 which is carried by the outer ends of theadapter members 5 comprises a frame including a pair of side arms 16which have one of their ends provided with fulcrum studs 17 receivedwithin bearing openings formed in the outer ends of the members 5.Connecting the other ends of the arms 16 is a cutter bar 18 which inthis case is formed of ar strip of sheet metal having a suitable gaugeto provide for the necessary rigidity and weight to the cutter frame. Yfull length of the roll 14 has its ends provided with down-turnedflanges 19 which are attached to the inner surfaces of the arms l6-inany Wellknown manner as, for example, by spot welding the same thereto.Formed with the upper longitudinal edge of the bar 18 is a dependingflange 20 which has its lower edge rounded and resting upon the paperroll. The opposite or lower edge 24 of the bar constitutes the cutterand may be turned downwardly or rounded slightly to proteot the hand ofthe operator and to strengthen the bar at this point. The rounding ofthe bar is however not essential from a cutting standpoint, as the edgemay be straight and serve equally as well.

Arranged below the top wall of the bar 18 and located near the upperedge thereof is a pair of rods 21 and `22 respectively over which thepaper 23 is trained to take a somewhat tortuous path with the rod 22acting to holdthe free edge of the paper spaced from the cutting edge.This spacing of the paper from the cutting edge provides for theconvenient grasping of the paper and enables the operator to take holdof the paper at any point throughout the Width thereof. If desired, thebar 21 may be made removable to facilitate the insertion or training ofthe paper between the rods.

To effect this removal of the bar, a pivoted spring finger 25 isprovided which is located exteriorly of one of the arms 16 and has itsfree end formed with a slight depression entering one of the bearingopenings formed in the arms for the rod. By swinging the finger 25 toone side, the rod may be pulled outwardly so as to free its ends fromengagement with the bearings, as will be readily understood.

In operation, it will be seen that as the operator grasps the free endof the paper and exerts an outward pull thereon, the paper will passunder the lower edge of the ange 20, over the rod 21 and under the rod22 until the desired length of paper has been unwound at which time thepaper is brought into engagement with the cutting edge and cut in theordinary manner. After the cutting operation, the paper edge will dropdown to a position shown particularly in Fig. 2 which is due to thearrangement of the rod 22 and the tendency of the paper to straightenout. Due to the character of the paper which is somewhat stiff, the samewill hold itself in engagement with the rod 22 and the free end thereofheld in an elevated position but yet spaced from the cutting edge of thebar. The ange 20 under which the paper is passed serves as a brake forthe roll, and prevents the paper from sliding back and becomingdisengaged from its connection with the cutter bar.

From the foregoing it will be seen that a novel support for a roll ofwrapping paper and a, cutting mechanism for the paper thereofY hasbeenprovided which has several outstanding advantages in The bar 18which extendsthe` that due to the construction thereof, the paper rollmay be mounted on various supporting surfaces such as on top of acounter, the under side thereof or upon a vertical wall and yet maintainthe cutting mechanism in its proper relation thereto. The cuttingmechanism thereof also has the advantage of being efficient in itsoperation and will permit the ready grasping of the paper edge withoutthe necessity of first turning the roll so as to advance the paper ashas to be done with paper cutters of ordinary construction. Due to theparticular arrangement of the paper relative to the cutter bar, thepaper is spaced from said bar throughout the full length thereof so thatthe paper may be grasped at any point of its Width thereby greatlyfacilitating the paper cutting operation.
